摘要

The need to maintain or sustain a product’s usefulness to or beyond its initial lifecyclernexpectancy is often driven by investment costs, market share, sales revenues, new productrnrelease schedules, standardization, uninterruptable usage, or declining budgets. A question thenrnarises as to how often to upgrade a product. Aside from these typically discussed rationales, thernpaper concludes that a viable approach is to consider the upgrade cycle that results in thernminimum cost based on quality. A general quality loss function was developed to investigate thernexpected quality loss for quality characteristics such as nominal-the-best, smaller-the-best, andrnlarger-the-better. It is shown that when a shape parameter is introduced into the loss function,rnproduct upgrade cycles can be managed to minimize the expected losses.
